ок, значи чисто нов модул се проваля с трясък при зареждане, и после отиваме на ниво пачове. Според мен колега polaana ти е малко рано, но така и така сме там. Значи ако ще пачваш сорса на модула (спри ме в момента в който не разбираш какво казвам) първо го копирай и работи върху копието. Т.е. трябва да копираш директория microdia. След което отиваш в новата копирана директория и си приготвяш пач. Това ще е копие от страниците които си публикувала от трите минуса (---) в началото до двата в края/ или до края. В случая:

Надявам се са публикували пълните пачове. Та целия този код записваш във файл с произволно име (примерно opit.patch) След което
И така докато реши да не дава съобщения за грешка.
От друга страна държа да кажа, че има значително по-лесен начин за разрешаване на проблема - нова камера. Желанието ти да го бориш докато тръгне е чудесно, но трябва да имаш представа защо го правиш: защото ти е интересно да го бориш, или защото искаш резултат. Ако е първото - вече си на верния път. Ако е второто - по-лесно ще е с някоя logitech, която работи.
